There are three gear lubrication methods in general use: (1) Grease lubrication. (2) Splash lubrication (oil bath method). (3) Forced oil circulation lubrication. There is no single best lubricant and method. Choice depends upon tangential speed (m/s) and rotating speed (rpm). At low speed, grease lubrication is a good choice.

To give some perspective, most bearing applications are inner ring rotating (over 95 per cent). As such, the focus of standard bearing design is for inner ring rotating applications. Most may not think that inner ring or outer ring rotation matters, but, outer ring rotating bearings are typically less reliable than inner ring rotating bearings.

The most common stainless steel is 304 alloy. It contains 18% chromium and 8% nickel. For gearing, 303 stainless is typically used. In 303 alloy, the chromium content is reduced to 17%, and 1% of the alloy is sulfur. Because of the addition of the sulfur, 303 alloy has improved machinability compared to 304 alloy.

Drilling Machine Definition: Drilling is a material-removing or cutting process in which the tool uses a drill bit to cut a hole of circular cross-section in solid materials. This is the most common machining process, one estimate is that 75% of all metal cutting material removed comes from the drilling operation.

13 Common Causes of Seal Leakage and Failure. Years ago, most pump shafts were sealed using rings of soft packing, compressed by a packing gland, but this type of shaft seal required a fair amount of leakage just to lubricate the packing and keep it cool. Then came the development of the mechanical seal, which accomplishes the job of ...

At the heart of the gear drive, gears turn in pairs, working together to transmit power to your application. Gear drives increase torque, reduce speed, and change direction of the rotating shaft. With so much relying on such a basic piece of equipment, it's imperative to start with a gear drive you can count on.
